some people might think that the plugin does not work.. but well. it does. works perfectly for tracking multiple sub-domains under 1 property id. do take note this is a forked version of a dated plugin, that plugin also works provided that you follow the instructions carefully on the developers's site. do also take note that if you have mapped domains (ie they are top level domains now)and you want to have its own unique property id this plugin also has the option for you to do that
